Ed Hennis f730af6e05 Review feedback from @gregtatcam: json string number parsing
- Change the parsing in numberFromJson so that if the resulting Number
  is not the same as the parsed NumberParts, then throw, because
  unexpected rounding occurred
- Add modified suggested test cases, and modify some existing ones,
  which test this behavior.

Basics

Utility functions and classes.

The module xrpl/basics should contain no dependencies on other modules.

Choosing an xrpld container.

  • std::vector

    • For ordered containers with most insertions or erases at the end.
  • std::deque

    • For ordered containers with most insertions or erases at the start or end.
  • std::list

    • For ordered containers with inserts and erases to the middle.
    • For containers with iterators stable over insert and erase.
    • Generally slower and bigger than std::vector or std::deque except for those cases.
  • std::set

    • For sorted containers.
  • xrpl::hash_set

    • Where inserts and contains need to be O(1).
    • For "small" sets, std::set might be faster and smaller.
  • xrpl::hardened_hash_set

The following container is deprecated

  • std::unordered_set
  • Use xrpl::hash_set instead, which uses a better hashing algorithm.
  • Or use xrpl::hardened_hash_set to prevent algorithmic complexity attacks.
